In a press release the company said it was acting out of an "abundance of caution," and was working with state and federal officials on the reported illnesses. The E. coli breakout was reported betweening Dec. 21, 2015 and May 3, 2016. While attempting to track the cause of the illness, CDC found that approximately half of the individuals reported making something homemade with flour at some point prior to becoming ill. Some reported using a General Mills brand of flour.

Based on the information that has been shared with General Mills, some of the ill consumers may have also consumed raw dough or batter, according to the press release.

The company warned consumers not consume any raw products made with flour. Flour is an ingredient that comes from milling wheat, something grown outdoors that carries with it risks of bacteria which are rendered harmless by baking, frying or boiling. Consumers are reminded to wash their hands, work surfaces, and utensils thoroughly after contact with raw dough products or flour, and to never eat raw dough or batter.

Although most strains of E. coli are harmless, others can make you sick. E. coli O121 is a potentially deadly bacterium that can cause bloody diarrhea and dehydration. Seniors, the very young, and persons with compromised immune systems are the most susceptible to foodborne illness.

Any consumers concerned about an illness should contact a physician. Anyone diagnosed by a physician as having an illness related to E. coli O121 is also urged to contact state and local public health authorities.
